These extracts with considerable antimycobacterial activity showed 50% cytotoxic concentration (CC50) ranging from 94 to 384 μg/mL. Thus, Cleistopholis patens and Cryptolepis sanguinolenta are primed for further studies and could afford novel drugs for the mitigation of buruli ulcer disease.

Paratuberculosis is an enteric disease caused by Mycobacterium avium sp. paratuberculosis (MAP) that affects mainly ruminant producing losses to the livestock industry. Many molecular epidemiological methods have been used to discriminate MAP isolates. The aim of this study was to describe the genetic diversity of the Argentinean MAP isolates using a combination of two molecular systems, the mycobacterial interspersed repetitive unit-variable number tandem repeat (MIRU-VNTR) ("automated and "non-automated") and the multi-locus short-sequence repeat (MLSSR) system. Thirty-two isolates were identified as MAP of C type by IS900 polymerase chain reaction (PCA) and IS1311 PCA-restriction enzyme analysis. The main patterns found by both MIRU-VNTR systems were INMV1 (54.5%), INMV2 (24.2%) and INMV11 (9.1%). The INMV5, INMV8 and INMV16 were represented with one isolate each (3.0%). Only 4 MIRU-VNTR loci were polymorphic. Those isolates sharing the same INMV patterns were analyzed by MLSSR, being locus 2 the most polymorphic one showing isolates with 9, 10, 11, and more than 11 "G" repeats. Besides, the global discriminatory power among isolates could be increased using both techniques. Based on these results, a short version of the "automated" MIRU-VNTR could be used as a screening tool to group isolates genetically related and subsequently perform the SSR using locus 2 on those isolates sharing the same INMV pattern.

Nontuberculous mycobacteria (NTM) form two types of biofilms Bottom biofilm and pellicle. The spatial distribution of cells between these types of biofilms and their dispersion into the liquid medium depends on the ratio of the nutrient components of the growth medium. The inhibition of biofilm formation by NTM can be achieved through the use of lipophilic compounds, such as essential oils (EOs). The biofilm and pellicle formation of Mycobacterium smegmatis and Mycobacterium avium on four nutrient media under static conditions and in the vapors of six EOs was evaluated by conventional method. The antimycobacterial effect of EOs was also studied by the disc diffusion method. The bottom biofilm and pellicle formation of NTM largely depended on the composition and availability of nutrients. Nutrient media in which NTM form powerful bottom biofilm or pellicle or both have been determined. The growth of studied NTM strains on agar was highly sensitive to the EOs of Scots pine, Atlas cedar, bergamot, and a mixture of EO of different plants. The cultivation of bacteria in the EO vapors also resulted in total suppression of the pellicle for all studied NTM strains. Our data clearly indicate that the carbon-nitrogen ratio is involved in the regulation of the spatial distribution of the biofilm. The preventing effect of EOs vapors, especially the synergistic action of mixture of EOs on the biofilm and pellicle formation by NTMs can be observed.

Japan has successfully reduced the burden of tuberculosis (TB) in the past seven decades; however, there are still some issues in eliminating TB. Its presence in immigrants, particularly multidrug-resistant (MDR) TB, is one of them. In mid-September 2019, a teenage Chinese male student in a morning class of a Japanese language school in Tokyo, Japan, was diagnosed with sputum smear-positive pulmonary MDR-TB. The outbreak cases were analyzed in a cohort study. We investigated 138 students and 18 teachers, of whom 81 (51.9%) were male, 115 (73.7%) were aged from 20 to 29 years, and 124 (76.9%) were from China. Four other students in the same classroom and another in a different classroom from the index patient in the morning classes were also diagnosed with MDR-TB disease by the end of November 2020. In addition, 31 cases of latent TB infection (LTBI) were detected among the students and teachers. Students in the same classroom had the highest risk of TB infection (78.9%, 95% confidence interval [CI] 54.4%-93.9%) with a relative risk of 8.6 (95% CI 3.9-19.0), followed by students in the other classrooms of the morning classes (25.9%, 95% CI 15.0%-39.7%) with a relative risk of 2.8 (95% CI 1.2-6.8), compared with the afternoon class students (9.2%, 95% CI 3.5-19.0) who had minimal contact with the index patient. National TB programs should adopt prophylaxis regimens for MDR-TB LTBI cases and provide prophylaxis to them, particularly if related to an outbreak. The Japanese government should screen immigrants for TB, particularly those from TB-endemic areas.

"Quality of life (QOL)" is relatively a new concept, which originates from the World Health Organization (WHO) "health" definition. The WHO defines "health" as a state of complete physical, mental, and social well-being and not merely an absence of disease or infirmity. It introduces a word, "well-being," which has two components, one the objective component and the second subjective component. The objective component mainly includes all the material possession by an individual, whereas the subjective component includes the perception of health by an individual, i.e., "QoL." It has been observed that most of the persons affected by Hansen's Disease (leprosy) have good economic conditions, but they continue to suffer from social, psychological, and physical problems which makes their life miserable. Hence, an attempt has been made to assess their QOL and factors determining them. A convenient sampling technique was used and 114 persons affected with Hansen's disease were studied. The study was conducted for a period of 1 year from November 2012 to October 2013.
